This benchmark evaluates a Green Agent designed for the AgentBeats competition that assesses Purple Agents on their ability to perform core data wrangling and schema alignment tasks. Specifically, it measures how effectively an agent can identify primary and foreign keys, detect joinable columns across tables, resolve naming inconsistencies, and merge fragmented schemas into a coherent, standardized representation. The benchmark focuses on structural reasoning over relational data rather than surface-level formatting, capturing an agent’s capacity to infer how disparate datasets should be correctly connected.
